CVE-2021-47235

CVE-2021-47235 affects the Linux kernel net/ethernet path: ec_bhf_remove() uses priv (netdev private data) after free_netdev() is called, enabling a use-after-free. The fixed sequence moves free_netdev() to occur after the PCI I/O unmaps (pci_iounmap) of priv, preventing access to freed memory. D...
